Thank you for the compliments! <3
So, about the explanations - I don't really know who would play this game if it was released and completed, so just in case someone doesn't know about how those math concepts work, they would learn very quickly. For example, I tested the game with my sister (shes 3 years younger than me) and she didn't know about factorials. But after the explanations, she did the test with no problem!
